Omega Kerfur book doesn't have a recipe. Even when I have the book on the crafting bench the kerfur pelvis just doesn't appear as a crafting option no matter how many different kinds of scrap I pile onto it.
You actually need to follow the other manual, the one in the form of a binder, to know the recipe of each given part. There is no definitive one-and-done option to build an Omega Kerfur. Each part needs to be crafted out of the items listed from this manual's pages, including regular Kerfur parts, joints, the radioactive core and the module.
The other manual, the one in the image your sharing, doesn't appear to serve a purpose at the moment. That or it still requires the binder manual, but I couldn't tell ya' since I just placed both on the table and just followed the recipe.
